夸克CKM混合矩阵的一个普适参数
Accurate Quark CKM Mixing Matrix in terms of one universal parameter
摘要:
夸克Cabibbo-Kobayashi-Maskawa混合矩阵是标准模型的一个基本组成部分,它被精确地确定以适合世界数据分析。本文通过一个小的无量纲参数的简单紧凑的参数化,CKM矩阵元素的高精度绘制。导出了KM CP破坏位相的唯一值-65.53度,与Wolfenstein参数化的拟合结果一致。随着三个混合角和CP破坏相位的定量确定,SM中CKM全局拟合的完整内容在小的相对1 S.D.内被准确地再现。以一个统一系统的形式存在。将夸克-中微子混合角互补的思想推广到Dirac CP-破坏相之间的关系中,用与已有数据一致的相同参数对中微子Pontecorvo-Maki-Nakagava-Sakata混合矩阵进行参数化,并将其与夸克CKM混合矩阵联系起来.
英文摘要:
The quark Cabibbo-Kobayashi-Maskawa mixing matrix is a fundamental part of the Standard Model accurately determined to fit world data analysis. In this paper the CKM matrix elements are high accurately rendered via simple compact parameterization by one small dimensionless parameter. Unique value of the KM CP-violating phase -65.53 deg is derived in agreement with fitting the data Wolfenstein parameterization. With the three mixing angles and CP-violating phase quantitatively determined, the complete content of the CKM global fit in the SM is accurately reproduced within the small relative 1 S.D. ranges in the form of a united system. Parameterization of the neutrino Pontecorvo-Maki-Nakagava-Sakata mixing matrix by the same parameter in agreement with available data is related to the quark CKM one by the idea of quark-neutrino mixing angle complementarity extended to the relation between Dirac CP-violating phases.
